sodium 2-oxomalonate - Introduction
mesoxalic acid disodium salt, also known as sodium dimethyloxalate (mesoxalic acid disodium salt), chemical formula Na2C2O4, is a crystalline colorless crystalline powder. The following is a description of its nature, use, preparation and safety information:
Nature:
1. mesoxalic acid disodium salt has good solubility and can be quickly dissolved in water.
2. It is an unstable compound, susceptible to moisture, and will gradually decompose when exposed to the air.
3. mesoxalic acid disodium salt can form ladder crystal hydrate, and the structure contains water molecules.
Use:
1. mesoxalic acid disodium salt can be used as an experimental reagent in academic research and used to synthesize other compounds.
2. It is often used as an intermediate for reducing agents or oxidants in organic synthesis.
Preparation Method:
mesoxalic acid disodium salt can be prepared by the following methods:
1. Carbonylmalonic acid is reacted with sodium hydroxide solution.
2. Carbonylmalonic acid reacts with sodium hydroxide to produce an intermediate of sodium carbonylmalonate, which is then converted into sodium dimethyloxalate by heating.
Safety Information:
1. mesoxalic acid disodium salt is less toxic to humans, it is still necessary to avoid swallowing or direct contact with eyes and skin.
2. Wear protective gloves and goggles during operation to avoid inhalation of powder.
3. storage should be sealed, avoid moisture and oxidation, to prevent contact with strong acid, alkali and other substances.
Please note that when traveling to the laboratory to use or handle mesoxalic acid disodium salt, follow relevant safety practices and comply with local regulations.
